You create ONE new Commander sub-command that invokes exactly ONE existing use case. You do NOT create use cases. You do NOT modify the DI container. You do NOT touch other commands.

Inputs (the caller MUST provide all of these)

1. command_path — where the .command.ts file lives under src/presentation/cli/commands/ (e.g., app/cloud-providers/connect.command.ts).
2. command_name — the sub-command name users type (e.g., connect, deploy, status).
3. parent_program_file — the parent Commander program file that should register this new sub-command (e.g., src/presentation/cli/commands/app/cloud-providers/index.ts).
4. use_case_class — the class name of the use case the command invokes (e.g., ConnectCloudProviderUseCase).
5. use_case_import_path — internal alias path (e.g., @/application/use-cases/cloud-deploy/connect-cloud-provider.use-case.js). Note: CLI commands use the @/* internal alias with .js suffix — NOT @shepai/core/*.
6. di_token — the string token passed to container.resolve() (e.g., 'ConnectCloudProviderUseCase').
7. args — list of { name, description, kind: 'argument' | 'option', required?: boolean, default?: string } for Commander. Mark option flags as --foo <value> for string options or --foo for booleans.
8. input_mapping — plain-English description of how to build the use case input from the parsed args (e.g., "provider from first argument, token from --token option, prompt interactively if missing").
9. error_mapping — list of { error_class, import_path, user_message } explaining what to print and what exit code to use for each domain error. Value imports MUST come from @/domain/errors/* (zero-dep targets). Never value-import from use-case files or port-interface files.
10. success_output — plain-English description of what to print on success (e.g., "green checkmark + Connected to <provider>").

If any required input is missing, return an error.
